OPERATING GATES.

ESPEGTFICATION forming part of Letters Patent No. 333,865, dated January5, 1886.

Application filed February 2, 1884. Serial No. 119,641. (No model.)

To all whom it may concern.-

Be it known that I, HANS F. KLoPP, a citizen of the United States ofAmerica, residing at Chicago, in the county of Cook and State ofIllinois, haveinvented certain new and useful Improvements in OperatingGates; and I do hereby declare the following to be a full, clear,

and exact description of the invention, such as will enable othersskilled in the art to.

5 gates, and more especially to that class of gates designed for use inconnection with a draw-bridge; and the said invention consists intheimprovements and combination of parts hereinafter set forth andclaimed.

. Inthe accompanying drawings, forming part of this specification,Figure 1 is an elevation of my improved gate and operating appliances,looking from the position of the drawer. Fig. 2 is an inverted sectionalplan on the line yy, Fig. 1. Fig. 3 is a section on the line mm, Fig. 1;and Figs. 4 and 5 are detail views.

A cross-bar, A, forms a port-ion of the abutment, and has mountedthereon vertical standards B C, which support horizontal bars D E E,which have secured at their outer extremities a bar, F. A guide-rail, a,is secured to each bar E at the inner side thereof, so as to permit apulley, b,journaled in a hanger, b, secured at one end of gates G G,located between the several standards and bars B C, D E E and F, abovedescribed, to rest on said rail. The lower forward end of each gate issupported by a roller, b, journaled in a bracket, b secured to the saidgate. The roller b rests, and is designed to travel upon, a guide-rail,0, extending transversely across the abutment A. The outer lower end ofeach gate G G is provided with a bracket or plate, d, which isperforated for the attachment of the end of two cords, d d. The cord dof the gate G passes from the bracket (1 over a pulley, e, secured onthe side of one of the standards, C, and then passes down through 50 thebase A, around a pulley (shown in dotted lines, Fig. 1) journaled in arecess in the said My invention relates to automatic sliding base, andis then secured to one end of aplate, H, sliding in a slot, f, formedbetween metal sections f f", bolted on the face of the abutment A. Thesaid plate H is provided with depending ears 9, (dotted lines, Fig. 3,)which rest in a guide-groove therefor, and is further provided with ashank or neck, 9', which projects through the slot f and carries avertical pin, The cord d passes around a pulley, e, journaled at therear end of the gate G, and thence over a pulley, e", at the forward endof the said gate, then down and around apulley, e and finally attachedto a plate, I, located in a lower plane than the plate H, but in allrespects similar thereto,with the exception that its ears i extendupward into a guide-groove therefor, instead of downward, as in theother case. The plate I is also provided with a shank, i, which extendsthrough a slot, f formed in the face-platef and carries a vertical pin,*6.

The arrangement of the cords d d on the gate G is the reverse of that ofthe gate G, the cord d in this instance passing around the pulleys e e"on the rear and front of the gate and down over the pulley (shown indotted lines to the right of Fig. l) to the plate H, while the cord (1passes directly to the pulley e and thence to the plate I by way of apulley, 0 upon abutment A. A plate, J, pivotally secured by a bolt, j,to the platesff is located above each end of the slots f f, and isretained in a position inclining toward the center of the base by aspring, j, one end of which is coiled around the boltj, while the otherend is looped to embrace one of the bolts j, that secures the sections ff to the base. Each plate J has a projecting portion, j, for a purposeto be described hereinafter. 90

The end Kof the drawer-section is provided with two brackets, is, eachof which has two parallel ribs, 7c,between which vertically plays aplate, L. Apin, k, located near the bottom of each plate In between theribs 7c, prevents 95 the plate L from dropping out. A pin, 1, is locatednear the bottom of one of the plates L, and a pin, Z, near the top ofthe other plate L.

The arrangement of the cords, pulleys, and plates A and I is such thatwhen the gates are opened, as shown in Fig. 1, the plate H is at thelefthand end ofthe upper slot, f,while the plate I is at the right-handend of the lower slot,f as seen in Fig. 1. The draw-section K then movesin the direction indicated by the arrow, Fig. 2, and the pin 1 of theplate Z, engaging the pin of the plate H, moves the same along the slotf toward the other end of said slot, resulting in traction on the rope dof the gate G and the rope d of the gate G, thus moving said gatestoward each other until they meet at the center of the base and closethe approach to the draw. When the gates meet each other, as abovedescribed, the plate H has arrived at the other end of the slot f, whenthe pin Z, coming in contact with the upper face of the plate J, travelsup said plate by reason of its plate L being elevated in its bearingsand drops over past the plate J, out of engagement with the pin of theplate H. The draw-section K then continues on until it is completelyopen. Upon the return of the drawer-section K the pin Z comes in contactwith the projection f of the nearest plate J, and, lifting said plateagainst the spring-pressure, again engages the vertical pin of the plateH, so that the continued movement of the drawer-section causes saidplate to return to its first position, and thus result in the opening ofthe gates.

If in the operation of opening the drawer the section K had been firstmoved in adirection opposite to that first above described,the pin l ofthe other plate, L, would have engaged the vertical pin of the plate I,and moved said plate to the opposite end of said s1ot,resulting in theclosing of the gates.

From the foregoing description it will be apparent that the constructionis such that a slight movement of the draw section K in either directionis sufficient to cause the complete closing of the gates G G, whichcannot be opened until the drawer returns to its normal position.

. as described.

2. The combination, with the sliding gates G G and the slotted plates ffupon the abutment A, of the cords d d, the plates H I, sliding in theslots of the abutment and connected by said cords to the gates, thevertically-adjustable plates L L, constructed to engage plates H I, thespring-plates J, and the pulleys for leading the cords from the slidingplates to the gates, substantially as set forth.

3. The combination, with the abutment A, carrying the platesff, withtheir slotsf f", the frame B O D E E F, the gates G G, and the pulleys,of the cords d (1 connecting plates H I with the gates, thespring-plates J, and the brackets 7c, carrying the vertically-movingplates L L, as specified.

4. The combination, with abutment carrying the gate-frame, the slidinggates, and the slotted plates, of the plates constructed to slide in theslots and provided with the pins, the spring-guides, and the bracketsmounted upon the draw and carrying the plates L L, having the pins Z Z,as and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.
